Description

FLT3-IN-15 is a highly potent and orally active FLT3 inhibitor with IC50s of 0.87 nM and 0.32 nM for FLT3 and FLT3/D835Y, respectively. FLT3-IN-15 can be used for researching acute myeloid leukemia[1].

IC50 & Target

IC50: 0.87 nM (FLT3), 0.32 nM (FLT3/D835Y)[1]
In Vitro

FLT3-IN-15 (compound 36) (0-100 nM) exhibits anti-proliferative activities against MOLM14 cell lines[1].
FLT3-IN-15 (0-1 μM; 72 hours) shows extremely more sensitive against MV4-11 cells than K562 cell line, and displayed good safety profiles against other cancer cell lines[1].
FLT3-IN-15 (0.01-1 μM; 4 hours) shows strongly blockage of the phosphorylation of STAT5 and Erk1/2 in MV4-11 cells[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
